In the first of November of 1755, a massive earthquake hit Lisbon. It was estimated intensity between 8.9 and 9.1 Richter (Japan in 2011 was 9.0 and Indonesia in 2004 was 9.1 scale).
It was the All Saints Day, a religious catholic holiday and big percentage of population was attending mass at the church. It was estimated up to 40.000 people lost their life on this tragic event, on a population of 200.000 people.
After the big earthquake, approx 40min later, a big tsunami came from the ocean. The tsunami was so huge that waves were felt in Martinique Caribbean and Barbados and hit with 20 metres (66 ft).
Following the earthquake and the tsunami, the city was burning for several days, mostly because of the candles from the churches.
Today is still visible the destruction of the earthquake on the city. You can see a reconstruction of this big disaster on the following movie below, showing what happened to the city:
